*.llMPRovYEMENT in.l HARvEsTER-RAKS.

To allI whom 'it may concern.-

Beit knownv that I, HENRY Picasa, `of Brockport,

, county of Monroe,-State of New York, have invented certain new and usetul Improvements in Harvester- Bakes, of which theibllowing is a full, clear, and oxnet description, reference vbeing had to the accompav nying drawing making a part of this specification, in

which a- 1 Figure 1 is a perspective view vot' a harvester platform with my improvements applied;

'Figure 2 is' a rearelevation oi' the same with the reel removed; and v l AFigure 3 is a perspective view of therake-shipping device, detached.

vSimilarletters of reference denote corresponding paits in al1 the figures.

My invention relates to that class of machines which 4"employs an overh ung reel, and in connection therewith .a continuously-rotating rake, which strikes -into the standing grain in front of the cutters and assists the `reel-beaters in picking up the grain and presenting the same to the cutters, after which it passes underneath the reel-shaft and sweeps over the platform in the are of a horizontal circle, ior discharging the grain behind the main frame and out of the way ofthe team and machine on the succeeding' round; and

It `consists-- First, mounting the horizontal reel-shaft in an adjustable yoke, which is supported upon a stationary reel-post, the rake being driven -from a sleeve surrounding reel-post, in such manner that, by vertically adjusting the yoke upon' the post and changing the size of the bevel-wheel upon the reel-shaft, the speed of the reel may be changed; and I may, also, by .swinging the yoke horizontallyupon the post, change the vertical plane occupied by the reel, for the purpose of adjusting its angle of rela-tion to theeutting apparatus.

Second, in the construct-ion and arrangement of the clutch or shipping device, for controlling the rake and making it independent ofthe reel.

Third, in combining with the rake-arm a hook (or hooks) which engages with the shipping device while the rake is traversing the cam-guide qu its return movement, and prevcntsthe rake from being accidentally thrown out of gear and from becoming caught by and entangled with the. reel.

Fourth, in locking the rake-arm to and carrying-it upon the face et' the gear-wheel while the rake is sweeping the platiorm.

. Fifth, in an arrangement of spring catch for holding the rake down upon the platform while sweeping over the same, in combination with atripping device i'cr releasing the rake and allowing it to rise after-the grain is discharged.

In the accompanying drawingrepresentsy the platform, which. is made and applied in rear ot' the cutting apparatus'inany usual manner. l

B is thc reel-post, mounted upon the inner front 1 corner ot' the platform, ornpouthe main-frame shoe.

or finger-bar, or an extension thereof; and

B', the base-plate or flange, by means of which the.;v post B isl rigidly attached to the bar or other support,` said plate B' also serving as ythe step or support for the gear-sleeve C, mounted on shaft or post B.l

lSleeve Chas keyed to it, near its lower end, a bevel- 1wheel, I), through which motion is imparted'to the` sleeve from a `bevel-wheel, D, driven from the main driving-wheel or axle of tthe machine in any usual manner.

On the upper end of post B is mounted a tubular arm or yoke, E, expanded in widthaud slotted,at E', to ncconnnodnte a bevel-pinion, D3, on the inner end ofthe reel-shaft F, which is mounted in the sleeve of yoke 1*],and to which motion is imparted, through bevel-pinion 1)", from a bevel-wheel,'1)2,'on the upper end oi'gcar-sleeve (i.

The arm or yoke E may be set and held'at the proper height, and with the reel-shaft and beaters at any desired angle to the path of the machine, by means of a set-screw,

G is an inclined cam-way or track surroumiing the post B; and

I-I is a box or hub mounted loosely on the gearsleeve C, above the bevelwlieel D, said box being provided with pivots or trunnions, h, on its opposite sides,

' upon which the rake-arm or straps I are hung in such manner as to be free to vibrate to provide for-the necessary vertical movements of the rake.

'J is a tubular clutch or shipper surrounding the lower end of gear-sleeve'O, and provided with upright arm or hooks, j, which pass through slots or perforations in the bevel-wheel I), and enter notches in the lower face of box H, underneath the rake-pivots h, said arms engaging with the bevel-wheel and causing the clutch to be rotated therewith, and also serving, when engaged with the box H, to rotate said box and the rake carried thereby.

The shipper-sleeve J is groovcd at j, and a forked or crescent-shaped ange, k,`on the upper end of a vertical slide-rod, lr, engaging inthegroovej, serves, when slide-rod It is moved up or down, to engage or disengage arms j with the box or rake-carrier H.'

Y A spring, 7a2, surrounding slide-rod 7.1', sel-vesto hold the slide up, with the clutch engaged with the rakeearrier or box II.

' The lower end ot'slide .It may be connected with any suitable arrangement oi' hand-lever or treadlc, placed in convenient position to be operated by the hand or foot of the driver ridingon the machine.

The upper ends of shipper-arms or uprights 7' are 'ovided with horizontaly ears or hooks, j, and the bke-arms or straps I are provided, at their heel or .vot end, with hooks, fi, which, when the rake is raised r a certain height on its return or backward movelent, pass underneath the hooks jt, and thereby vpreent the rake from being accidentally thrown out of ear, and insure its approach to the .reel in its de- :ent into the standing grain' in uniform relation to ie reel-beaters. A

The cam-way or track G drops out of. the path of ie rake-arm, or, if preferred, it may be left open on 1el side adjacent to the platibrm, so that, after the ike' reaches the platform, therake-arm, instead of zsting upon the cam, will rest upon and becarried y the bevel-wheelD, .thereby preventing any stoping or back action of the 'rake in the event of its bc-4 ig thrown ont of gear, either accidentally or otlfer- 'ise, during its passage over the platform.

gis a spring-latch attached to the rake-arm, and erving, by catching underneath the wheel I) when he rake-arm rests thereon, to lock the rake-arm to he wheel, and thereby to insure the .movement of' the ake-arn with the wheel.

g' is an upright standard or iripper, provided at its `pper end with 1an inclined face, against which the )wer end ot' the spring-latch f/ presses alter the rake.

las passed over the platform, in such manner as to elease the latch and allowthe rake to riseA upon the am for its return movement.

The operation of the several parts will be readily 4the upper end of the rake and gear-sleeve, and the bevel-pinion Don the reel-shaft; and by snbstitilting gears of varying diameters' the reel may be made to make one or two (more or less) revolutions to one of the rake, as desired, and the speed of the rake will be govemed by the relative size of gears 'D D, subject to the control of the driver through the shippingdevices described.

Having now described my invention,

What I claim as new, and desire to secure by Lctv1. The adjustable yoke E, supporting the reel, in-

`arm I and carrying-wheel D, for locking the rake-armdown during its passageover the plat-form, as described. v 5. The tripping-standard g', in combination with the lspring-catch g, arranged and operating substantially as described.
